Introduction: Diabetes Mellitus (DM) is always a multifactorial metabolic disorder having a wide range of abnormalities in carbohydrate, lipid and protein metabolism. Dyslipidemia is a natural process of DM causing abnormal variations of different lipoproteins and it is one of the significant risk factors for Cardiovascular Disorder (CVD). There is a need to closely evaluate newer approaches in case of DM because even if dyslipidemia is treated, there is always a risk of CVDs in DM patients because of the hyperglycemia itself. So, lipid abnormalities should be assessed aggressively and treated as part of diabetes care. Apolipoprotein B100 (Apo B100), Apolipoprotein A1 (Apo A1) and Lipoprotein (a) {Lp(a)} are newer markers which are always welcome and necessary as many of the reported cases with normal conventional lipid profile have developed cardiac events.

Aim: Study the correlation between glycemic control and the levels of Apo A1, Apo B100 and Lp(a).

Materials and Methods: Total 56 patients of (DM) diagnosed on the basis of American Diabetic Association guidelines were recruited, out of which 28 were identified as uncontrolled-diabetic patients and remaining 28 as controlled-diabetics on the basis of Glycosylated HbA1c (HbA1c). The control group consisted of normal healthy 28 individuals. Apo B100, Apo A1 and Lp(a) along with traditional lipid profile, FBS and HbA1c were estimated in all the subjects.

Results: Apo B100/Apo A1 ratio and Lp(a) levels showed highly significant difference (p-value <0.001) between uncontrolled diabetics, controlled diabetics and healthy Controls. Apo B100/Apo A1 ratio and Lp(a) showed significant positive correlations with HbA1c (r= 0.494, p <0.0001) and with each other.

Conclusion: Apo B100/Apo A1 ratio and Lp(a) show a highly significant positive relationship with glucose tolerance of the patients as reflected in the HbA1c values. If proper glycemic control is maintained, the levels of Apo B100/Apo A1 ratio and Lp(a) can be controlled as reflected by the lower levels of these parameters observed in controlled diabetics in comparison to uncontrolled diabetics.
